となることがある。Problems to be Solved by the Invention In a dryer for drying grain, a burner installed at the front of the dryer combusts combustion fuel while jetting it forward in a combustion chamber, and the combustion flame is sent to the rear of the dryer. The hot air is drawn across the drying room by being sucked in by the exhaust fan, and the crushed material flowing down through the drying room is transported to the drying room.
,-Vinegar 4Z N! The combustion heating temperature of the burner in the city varies widely depending on the amount of grain to be dried, the outside temperature, etc. For this reason, when the combustion heating temperature of the burner' is low, the combustion chamber is cooled by the outside air passing through the ventilation chamber on the outer periphery of the combustion chamber, which deteriorates the vaporization state of the combustion fuel. If poor combustion occurs or the combustion heating temperature of the burner is high, the combustion chamber will be overheated more than necessary unless the combustion chamber is cooled with outside air passing through the ventilation chamber. As a result, the vaporization state of the combustion fuel may become poor, resulting in poor combustion conditions.

常に安定した燃焼状態で燃焼する。Functions and Effects of the Invention The combustion fuel is combusted while being jetted forward in the combustion chamber (1), and is blown as hot air by the wind flowing around the outer periphery of the combustion chamber (2), but the combustion heating temperature of the burner is low and this Therefore, when the combustion chamber (1) section is cooled by the outside air passing through the ventilation chamber (2) and the temperature of this combustion chamber (1) section becomes low, the ventilation chamber at the outer periphery of this combustion chamber (1) (2) changes and guides the flow direction of the outside air passing through the combustion chamber (1) using a ventilation guide plate (3) to a state where the passing wind is difficult to hit the combustion chamber (1);
In addition, the combustion heating temperature of the burner is high, so the combustion chamber (1
) When the temperature in the combustion chamber (1) becomes high, the flow direction of the outside air passing through the ventilation chamber (2) on the outer periphery of this combustion chamber (1) is controlled by the ventilation guide plate (3). By changing the state to be easily exposed to the passing air, the combustion chamber (1) is not cooled more than necessary or overheated, so that combustion is always carried out in a stable combustion state.

態で燃焼する。By operating the front part of the dryer (4),
When this dryer (4) starts, the exhaust fan (8) at the rear rotates, and at the same time, outside air is sucked in from the ventilation chamber (2), the ignition heater (17) of the /Hena (5) is energized. The ignition heater (17) is then heated to red heat, and the combustion fuel is passed from the fuel tank (24) through the fuel pump etc. to the fuel nozzle (18).
) is supplied to the outer periphery of the scattering body (19), and this scattering body (I
s) to the inner wall of the vaporizer cylinder (20), and this vaporizer cylinder (2
0) The vaporizer cylinder (20) and vaporizer plate (21) are removed while flowing down the inner wall.
A part of this ejected fuel scatters onto the red-hot ignition heater (17) and automatically ignites to start combustion, and the combusting flame heats the vaporizing cylinder (20). , the fuel flowing down in this vaporization cylinder (20) is vaporized, and this vaporized fuel is formed between the injection hole of this injection a (I8) and this injection 1 (1G) and this vaporization a (21). A combustion flame is ejected from the gap, and this combustion flame becomes hot air, which is sucked by the exhaust fan (8) at the rear of the dryer (4) and crosses the drying room. The grains housed in the dryer are dried by being exposed to the hot air while flowing down the drying chamber, and when the grains reach a specified moisture content, the dryer is automatically controlled by the operation box (6). 4), but when the combustion heating temperature of the burner (5) is high, the combustion tube (14) is heated by the combustion flame, and this smoking tube (14) is automatically stopped.
4) When the temperature of the section rises above a certain temperature, the blower tube (
11) The ventilation guide plate (3) attached to the outer periphery by the mounting plate (13) falls forward due to the deformation of the mounting plate (13), and the ventilation guide plate (3) is held in the fallen state;
The flow direction of the outside air passing through the ventilation chamber (2) changes, and the outside air hits the combustion tube (14) well, thereby preventing abnormal over-ripening of the 1 nuclear combustion chamber (1). Ru. In addition, at the start of drying work or when the combustion heating temperature of the burner (5) is low, the temperature of the combustion tube (14) does not rise above a certain temperature, so the ventilation guide plate (3) is in an upright position. This prevents the combustion chamber (1) from being abnormally cooled by the outside air flowing through the ventilation chamber (2). Regardless of whether the combustion temperature of the burner (5) is low or high, the burner (5) always burns in a stable combustion state.
